"In New Orleans, even the police horses boogie out," the Facebook post says.

WDSU posted the video its Facebook page and it quickly gained the attention of locals who made comments about the city's culture. Some who commented were concerned that the horse was agitated and not enjoying the crowd. Others with knowledge of horses gave their own interpretations about its behavior.

A police spokesperson said horses in the Mounted Unit are trained for large crowds and Ace, the horse in the video, was not in distress.

The spokesperson said horses in the Mounted Unit often perform similar routines for small crowds. According to the Police Department's website, horses have to show the right mix of temperament and personality to join the Mounted Unit. Otherwise, they are returned to the original owner.

"It can take anywhere from a few months to a year of training to turn an adult horse into a Mounted Unit horse," according to the website.
